Time-varying phase noise and channel estimation in MIMO systems

Mehrpouyan, Hani; Nasir, Ali; Eriksson, Thomas; Blostein, Steven; Karagiannidis, George K; Svensson, Tommy

Description

Performance of high speed communication systems is negatively affected by oscillator phase noise (PN). In this paper joint estimation of channel gains and Wiener PN in multi-input multi-output (MIMO) systems is analyzed. The signal model for the estimation problem is outlined in detail. In order to reduce overhead, a low complexity data-aided least-squares (LS) estimator for jointly obtaining the channel gains and PN parameters is derived. In order to track PN processes over a frame, a new...[Show more]
